Abstract

This presented work is based on application of two multivariate calibration methods for simultaneous UV-VIS spectrophotometric determination of active substances in combined pharmaceutical formulation composed of Atorvastatin calcium (ATV) and Ezetimibe (EZT). The methods used were Principal Component Regression (PCR) and Partial Least Square (PLS). The Spectra of ATV and EZT were recorded at concentrations within their linear range 5.0-30.0 μg/ml for both drugs. 28 set of mixtures were used for calibration and 08 set of mixtures were used for validation in the wavelength range of 230 to 260 nm with the wavelength intervals λ= 0.5 nm in methanol. The methods were validated as per International Conference on HarmonizationQ2 (R1) (ICH) guidelines. These methods were successfully applied for determination of drugs in pharmaceutical formulation (tablet) with no interference of the excipient as indicated by the recovery study results. The proposed methods are simple, rapid and can be easily used as an alternative analysis tool in the quality control as well as in process control of drugs and formulation.

Abstract

A simple, sensitive and accurate stability indicating HPTLC method has been developed and validated for estimation of Dextromethorphan hydrobromide in bulk and pharmaceutical dosage form. The drug was spotted on precoated silica gel 60 F254 aluminum plates using Toluene: Methanol: Triethylamine (8.5:1:0.5 v/v/v) as mobile phase. The retention factor (Rf) was found to be 0.60±1.92. The detection of band was carried at 225 nm. The drug was subjected to different stress conditions like acid, base, neutral hydrolysis, oxidation, thermal degradation and photolysis. The method was successfully validated according to ICH guidelines Q2 (R1). The data of linear regression analysis indicated a good linear relationship over the concentration range of 2000-20000 ng/band with correlation coefficient 0.991. The method found to be accurate as results of the recovery studies are close to 100 %. The developed method was found to be simple, sensitive, selective, accurate and repeatable for analysis of and can be adopted for routine analysis of drug in bulk and pharmaceutical dosage form.
